Both of my superchargers came with different disharge manifolds. This is the one to use if mounting it like mine. The bolt pattern only lets them fit one way. I just whacked off the curved end and now it clears. I ordered a 90 degree silicone hose elbow to connect it to the VW intake. Using the Japanese part is going to work out cleaner because of the limited space. It'll give the best flow as it funnels the rectangular flange into a usuable tube.

A lot of people complain that there's no room to pull out the oil filter cartridge with the bigger Fram. I'm just going to make my hoses with a tad more slack and make the whole thing quick release. I can leave the hoses on and just bring the can away from the firewall enough to change the filter. The early cars like this have that goofy rain drain under the back window that make it harder to lift the filter element straight up anyway. Then, there's the fact that the 40hp shroud is a little wider than 36hp.... Even the smaller FP-3 might not fit perfect.

Here's a Fram filter I scored dirt cheap on eBay. It came off a tractor and is the bigger FP-4 model IIRC. I like the orange for a period correct build, but didn't think it complimented this car very well. What's cool is the can has a cool wrinkle texture that's covered up with the thick orange paint. I shot it in base/clear and put the repo decals under the clear so they don't fall off. My decal placement isn't perfect, but the originals were slapped on without a care. The "inlet" sticker was put on at almost a 45 degree angle.

The mock up 40hp case was put back in the car for a final double check on supercharger fit before I go further. In this position, the pulley is perfect with about 1/2" of clearance between the decklid. The little wiring bend tab for the license plate on the back of the decklid was almost touching, so I did have to remove it. I may trim the license light mounting studs a little to give the pulley more clearance. I've never owned a Judson, but it looks like this thing fits about the same lengthwise. It's just the oval shape of it that interferes with the distributor and intake manifold.

Once the original carb mount on the manifold was removed, I needed to adapt my own pieces. When I ground back all that cast aluminum, I wasn't expecting a ton of brazing that needed to be removed. I thought it would just be a small hole, but ended up being a huge oval. If I knew that, idve just welded the preheat tubes to a new piece of tubing for the center section. Instead of trying to adapt round tube to the wierd oval, I capped it with a new piece and drilled a 1" pilot hole.

At this point, I'm not concerned about the diameter of the lower pulley, one just needs to be there for alignment. The guys at the local NAPA let me rummage through boxes FULL of pulleys and have whatever I want. There was a pretty good variety from decades of pulley swapping on alternators for customers. I came across this monster that has a lot of potential. It's an 8 rib that will allow to to align a 4 rib belt at any position I choose. That will be dictated by decklid fit. I need to stick with a narrow upper pulley or it hits the back of the license plate light. I've already verified this. The supercharger was designed to use the 4 rib, so that will stay. I also chose to do a dual belt setup because I believe it will be easier to control belt slippage by not asking the same belt to turn the cooling fan. The downside is the supercharger must be closer to the decklid. A project like this is full of compromise so you just have to weigh your options. So far I'm getting everything I want and my compromises are that I must use a 4 rib belt and crank fire ignition. I'm happy with that.

This car has always ran an electric fuel pump, which I prefer, so no issues making mounting brackets with those studs. Because of the stereo, I also know I'm sticking with an alternator. I wanted to keep the 009 distributor and run the CB Black Box for simple timing control, but it's clear that it's just not going to fit. I have no choice but to go with crank trigger, but that is a blessing in disguise as long as you're not afraid of it. I'm not interested in EFI at all down the road, so I'll probably install EDIS and Megajolt and just tune fuel with my wideband. These brackets will let me do whatever I want. With the distributor gone, I'll have an easier time setting up a belt tensioner.
I have no idea what crank pulleys I'll end up with but this one works well for mockup because the face is totally flat. I can use a straightedge across the front of it to line up the supercharger upper pulley to it. The last thing I want after the car is painted is belts and broken parts flying at the back of the decklid. Proper belt alignment is critical, as everything is a super close fit.

I really hate doing things twice. I'm nowhere near ready to do the engine build yet, but I have a lot of fab work ahead if me. An empty mockup engine is much easier to deal with too when trying to get everything to fit.
My goal is a nice driving 40hp with more top end power and torque. I'm not looking to push any limits, probably 7lbs of boost or so. My other requirements are that it must fit under the early decklid and stay carbed. I'm a fan of EFI but a roots supercharger is a good match with a draw through carb.
Here is a later single port manifold center, with 40hp manifold ends installed as a slip fit for now. I know I'm going to be stroking the engine, so it's a big mistake to weld these areas until the final width of the completed engine is known. For now, I just need a mounting platform that is strong and has preheat.

Here is the supercharger. It's an AMR500 made by Aisin for Japanese market economy cars. You can also find these in other countries like Australia. They are pretty inexpensive in used condition on Ebay. Japanese wrecking yards are full of them, due to the fact that they don't allow high mileage engines on their roads.
The ebay seller I got this one from didn't package it very well. Although it got to my house in 3 days by air mail, it's kind of pointless if you don't keep it from banging around in the box. It spins freely 90% of the way, then jams up. The seller was quick to send me another. This one spins freely but has a dented pulley.  So, now I have a parts unit with a good pulley that's perfect for mockup. You have to fully expect pulley replacement anyway though with custom fitting and changing boost pressure.

Wiper assembly almost finished. IIRC, it's a 67 2 speed self parking motor on the early frame. I'm going to replace the linkage bushings and maybe the shafts, they are ok but one is worn a lot more than the other.
I cleaned up the motor cover with a Scotch Brite. After seeing how nasty the inside of my single cab's motor was, I decided now is the time to refresh this one. Removed the plate that holds the gears in place on the back, scraped old grease out and re packed with synthetic good stuff. The OG brown grease dries out and that causes binding and breakage to the sensitive plastic gear.
